Introduction

This map shows the spatial distribution of the U.S. population living in either a coupled opposite-sex or same-sex households. “Coupled” for this analysis means living in a household with either a married spouse or an unmarried partner present.

Unless otherwise noted, all information was collected from the 2019 American Community Survey (ACS 2019) through the Census API at http://data.census.gov.
